Atmospheric and Geodesic Controls of Muon Rates: A Numerical Study for Muography Applications
Instruments, 2022 Muon tomography or muography is an innovative imaging technique using atmospheric muons. The technique is based on the detection of muons that have crossed a target and the measurement of their attenuation or deviation induced by the medium.

Development of the very long-range cosmic-ray muon radiographic imaging technique to explore the internal structure of an erupting volcano, Shinmoe-dake, Japan [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2015 Muography offers us a tool to observe hazardous erupting volcanoes remotely. However, practical muographic observations of volcanoes from a distance are difficult; therefore, various observations have been performed in the vicinity (< 1.5 km) of volcano ...

Muon Radiography Investigations in Boreholes with a Newly Designed Cylindrical Detector
Instruments, 2022 Muons are constantly produced in cosmic-rays and reach the Earth surface with a flux of about 160 particles per second per square meter. The abundance of muons with respect to other cosmic particles and their capability to cross dense materials with low ...

Gaseous Detectors for Field Applications: Quality Control, Thermal and Mechanical Stability
Instruments, 2022 A cosmic muon imaging system is essentially a particle tracking detector as known from experimental High Energy Physics. The Multiwire Proportional Chamber (MWPC) once revolutionized this field of science, and as such it is a viable choice as the core ...

Borehole muography of subsurface reservoirs. [PDF]
Philos Trans A Math Phys Eng Sci, 2018 Imaging subsurface rock formations or geological objects like oil and gas reservoirs, mineral deposits, cavities or even magmatic plumbing systems under active volcanoes has been for many years a major quest of geoscientists. Since these subsurface objects cannot be observed directly, different indirect methods have been developed.

Distance of flight of cosmic-ray muons to study dynamics of the upper muosphere [PDF]
Geoscientific Instrumentation, Methods and Data SystemsThe Earth can be divided by main layers, including the atmosphere, geosphere (solid Earth), and biosphere, depending on its predominant component. In this work, the layer of the Earth which constantly contains a high concentration of muons (∼8×1012 muons)

The effect of shielding material density in muon tomography
Jurnal Fisika Flux, 2023 In recent years, the use of high-penetrate cosmic-ray muons has been used in many applications to investigate the internal structure and composition of large material. The muon attenuation is based on multiple Coulomb scattering.

Geant4 Simulation of Muon Absorption in Concrete Layers
Instruments, 2023 Muography requires a detailed understanding of the absorption of muons in the material situated between the muon source and the detector. A large-statistics (>3 billion event) Geant4 simulation was run to simulate the absorption of muons in different ...
